Claims.

This invention relates to improvements in shoes and particularly to thesecuring of shank pieces in shoe bottoms other than by driven metallicfastenings.

The present application is a division of a copending application SerialNo. 622,691, filed July 15, 1932, which is directed to improvements inthe manufacture of shoes. It is an object of the invention of saidapplication to provide a method of manufacturing shoes such that theheel seat portion as well as the shank and forepart may be lasted, theoutsole attached to the heel seat, and the heel attached without thepresence in the finished shoe of metallic or other driven fastenings. Asan aid to the attainment of that object, the shank stiifener of theshoe, as disclosed in said application and as illustrated and claimedherein, instead of being secured to the insole by a tack or tacks inaccordance with usual practice, has its rear end held by a filler piecesecured to the heel seat portion of the shoe. This filler piece, whichmay be made, for example, of hard fibre board, is preferablyapproximately U-shaped in outline to conform to and be received withinthe area bounded by the edge of the over-lasted portion of the shoeupper at the heel seat of the shoe. As illustrated herein, it is securedby cement to the insole of the shoe, with the rear end of the shankpiece received in a recess formed in the forward end of the fillerpiece. Thus the shank piece is held securely in place in the shoewithout the presence of' metallic fastenings.

With the above and other objects in view the invention will now bedescribed with respect to the accompanying drawing and pointed out inthe claims.

In the drawing,

Fig. 1 is a perspective view of a shoe illustrating the condition of itsbottom after it has been lasted, with a metal shank piece the rear endof which projects under a filler piece in accordance with the invention,tacks being shown to hold the filler piece in place while the cement,

by which it will be permanently held, is setting;

Fig. 2 is a perspective View of the filler piece on a larger scale; andI Fig. 3 is a perspective view partly in section of the shoe after itssole has been attached, showing the manner in which the shank piece issecured in place by the filler piece.

The shoe in of the drawing isv illustrated as comprising an insole l2,an upper M and an outsole IS, the shoe as shown in Fig. 1 having beenlasted and the marginal portion l8 of its upper prepared for theattachment of its sole in the manner disclosed in said parentapplication Serial No. 622,691.

In order to secure the usual metal shank stiffener 84 (Figs. 1 and 3)without the presence of metallic fastenings and at the same time to fillup the U-shaped space inwardly of the overlasted marginal portion of theshoe upper at the heel seat portion of the shoe, a filler piece 86 isprovided. This may be of hard fibreor other suitable non-metallicmaterial having an approximately U-shaped outline, shown in Figs. 1 and2, to conform to the space within which it is to be received and moldedor otherwise shaped to provide a recess or depression 88 at its forwardportion for the reception of the rear end of the shank piece 84.Pyroxylin cement, which has previously been applied at the heel seatportion of the insole and permitted to dry, is activated with a suitablesoftener, for example such a softener as that disclosed in LettersPatent of the United States Nos. 1,959,320 and 1,959,321, both grantedMay 15, 1934, on applications filed in the name of Walter H. Wedger. Theinsole engaging surface of the filler piece 86 is also coated withpyroxylin cement and the filler piece is secured in position, coveringand holding the rear end of the shank piece 84, by tacks 90 which arepreferably toed inwardly the better to hold 7 leaving the shankstiffener 84 secured solely by cement.

If the sole of the shoe is to be cement attached, the exposed surface ofthe filler piece may be coated with pyroxylin cement which is allowed todry and the outsole i6 cement-attached in known fashion, any suitablefiller being used at the forepart of the shoe, as may be desired. Itwill thus be seen that the finished shoe is free from metallic shankpiece attaching fastenings.

While the invention of this application was developed for and isparticularly desirable in connection with the manufacture of shoes thebottoms of which are free from metallic fastenings, it should beunderstood that its utility is in no way limited to use in connectionwith shoes of that type since obviously, if desired, shank pieces may beattached in accordance with the present invention in the manufacture ofother types of shoes. I

l-lavlng thus described the invention what is claimed as new and desiredto be secured by Letters Patent of the United States is:

l. A shoe having a shank stiifener with its rear end retained in adepression molded in a nonmetallic filler piece secured by cement in theheel seat portion of the shoe.

2. A shoe having an insole, an outsole, and a shoe bottom part locatedbetween the insole and outsole, said part being formed with a recess,and a shank stiffener having an end portion located in said recess andsecured therein by cement.

3. A shoe having a shank stiffener with its rear end retained withoutthe aid of metallic fastenings in a recess formed in a non-metallicfiller piece secured by cement to the heel seat portion of the insole ofthe shoe.

4. A shoe having a shank stiffener the rear end of which is received ina recess formed at the forward end of a filler piece secured by cementto both the insole and the outsole of a shoe at the heel seat portionthereof and within the area bounded by the edge of the overlastedmarginal portion of the shoe upper.

5. A shoe having a shank stiffener the rear end of which is received ina recess formed in the insole engaging surface of a filler piece securedby cement to both the insole and the outsole of the shoe at the heelseat portion thereof and within the area bounded by the edge of theoverlasted marginal portion of the shoe upper.
